COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 573,136, dated December 15, 1896.

Application filed January 23, 1396- Serial No. 576,500. (No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL J. CABLE, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered a new and useful Improvement in Combination-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this application, in which Figure 1 is a View in perspective of my lock applied to a detached portion of a satchel. Fig. 2 is a plan view of the top portion of the lock on an enlarged scale. Fig. 3 is a vertical longitudinal section taken on the line III III of Fig. 2. Fig. 4 is a partial longitudinal section similar to Fig. 3, showing the central locking-plate and pins in a lowered position. Fig. 5 is a vertical cross-sectional view taken on the line VV of Fig. 2. Fig. 6 is a similar sectional view showing the parts in position corresponding to Fig. 4:, the hasp-plate being removed. Fig. 7 is a detached perspective view in detail of the central locking-plate and pins mounted thereon with the vertical stud and push-button. Fig. 8 is a plan View of one of the dialplates in position 011 the octagonal stud carrying the register-plate, part ofthe construction being removed, on the line VIII VIII of Fig. 3. Fig. 9 is a plan view of one of the registerplates, the upper part of the stud being removed, on the line IX IX of Fig. 3. Fig. 10 is a horizontal sectional view of the lockingplate in engagement with the hasp-plate, the section being indicated by the line X X of Fig. 5.

Similar numerals refer to like parts wherever used throughout this specification.

Referring now to the drawings, 2 3 represent the two sides of a satchel in a closed position, the side 2 having firmly secured to it by means of bolts at the lock-inclosing case 5 and upper plate 6, and the side 3 having secured to it by any desirable means, preferably by screws 7, the hasp-plate 8, having therein the slot 9. Mounted in the central part of the case 5 is the vertically-adj ustable locking-plate 10, secured to a stud 11, the lower end of which, 12, extends through and has a bearing in the lower plate 13 of the case 5, and the upper end of which, 14, extends through the plate 6 and constitutes a pushbutton. Surrounding the lower stud 12 is a coiled spring 15, which normally holds the plate 10 in an upper or looking position, as shown in Figs. 3 and 5, the upward motion being limited by a shoulder 16, bearing against the edge of a plate 17, forming part of the case 5.

Plate 10 is provided along its front edge with an upturned lip 18, the outward face of which is rounded to facilitate the entrance of the hasp-plate 8, the face of which is also similarly rounded. A slot 19 for the entrance of the hasp-plate is made in the face of the case 5, corresponding in dimensions to the size of the hasp, so as to permit it to easily ride over and depress the lip 18.

Located at each side of the center stud 11 are two vertical studs 20, having reduced eX- tensions or stems 21 at their lower ends, which also have a bearing in the plate 13"and to which are rigidly attached the circular register-plates 22, each having therein a hole 23, which in a certain position of the registerplates are brought into alinement with pins 24, projecting downwardly from the lower face of the plate 10. A series of blind holes 25 are located around the top surface of the register-plates, as shown in Fig. 9, for the purpose of confusing and preventing the opening of the look by one unfamiliar with the combination.

The upper portion of the studs 20 is re duced so as to leave a shoulder 26, which has a bearing against the plate 17, the reduced extension 27 passing therethrough and terminating in a polygonal reduced extension 28, from the center of which projects upwardly a screw-threaded stud 29, upon which is screwed a button 29, milled around its edge, and upon the polygonal extension 28 is placed the circular dial-plate 30, having a polygonal opening in its center corresponding to the size, shape, and dimensions of the extension 28. This dial-plate 30 fits neatly in a circular opening in the plate 6, as shown, and has on its face a series of figures or characters corresponding in number to the sides of the polygonal opening and to the number ofholes in the plate 22. At any predetermined point on the plate 6 a notch or mark 31 is made, so

that when each of the numbers or characters is brought successively into register with the mark 01 one of the holes in the plate 22 will be brought into alinemcnt with the pin 24:. It will be seen that in only one position of the dial-plate will the open hole 23 be in alinement with the pin 24, and when both holes are so in alinement, as shown in Figs. 3 and 4, the push-button lat may be depressed, thus withdrawing the lip 18 for unlocking, as in Fig. 6, or allowing the hasp-plate to be inserted for locking. Coiled springs 32 hold the studs up in position, shoulder 26 bearing against plate 17.

It is evident that more than one open hole may be made in the plate 22, in which case the lock will open with more than one combination; also, by removing the dial-plate 30 from the polygonal extension 28, turning it partially, and replacing it in another position a new combination can be quickly and easily made, thus making it possible to change the combination at will. I may, if desirable, change the number of characters on the dialplate, as, for instance, there may be six, in which case the extension 28 would be hexagonal and the open hole 23 would register with the pin 24 in one of the six positions.

In the lock illustrated in the drawings there are eight holes in the register-plate 22, eight figures on the dial-plate, and the extension 28 is eight-sided or octagonal, and the lock is set to open at 58, reading from the right.

It is obvious that the lock may be further modified by the use of more than two dials and register-plates, as three or four might be employed, if desired, thus giving a more elaborate and complicated combination, although for ordinary purposes I have found two quite sufficient.

The advantages of my invention will be appreciated by those skilled in the art. It is very useful and eifective as a means of looking satchels and similar articles, obviates the necessity of a key, is ornamental in appearance, durable, and not likely to get out of order, while the adjustability of the combination-dials gives it a wide range of possible combinations.

Changes and modifications may be made in its construction by the skilled mechanic without departing from my invention, since I do not wish to be confined to the exact construction shown in the drawings, but to include such variations as might be made from it without departing from its general principles. For instance, the pins 24 in plate 10 may be placed in the register-plate 22 and holes 23 be put in the plate 10 with equally good results.

Having described my invention and in what manner it operates, what I claim, and desire to secure by Letters Patent, is

1. In a lock of the class described, a vertically-movable locking-plate engaging a haspplate, and register-plates provided with openings for pins in the locking-plate, said pins entering the openings in the register-plates in a plane parallel with the vertical axis of said register-plates, when the lock is unlocked; substantially as set forth.

2. In a lock of the class described, a movable locking-plate provided with an upturned lip for engagement with a hasp-plate, a stem supporting the locking-plate having bearings in the case of the lock, one end of such stem constituting a push-button, a coiled spring surrounding the other end bearing against the bottom of the case and the locking-plate respectively; and register-plates provided with openings for pins in the locking-plate, substantially as set forth.

3. A combination-lock consisting of a vertically-movable locking-plate and a push-button for depressing such plate, and revoluble register-plates provided with openings within the periphery of the plates for pins in the locking-plate; substantially as set forth.

4. A combination-lock consisting of a vertically-movable springcontrolled lockingplate provided with downWardly-projecting pins, and revoluble register-plates provided with perforating openings for such pins within the circumference of the rcgisterplates, substantially as set forth.

5. A combination-lock consisting of a vertically movable spring controlled, lockingplate provided with an upturned lip and downwardly-projecting pins, and revoluble register plates provided with perforating openings for such pins, mounted on stems having bearings in the case of the lock and provided with dial-plates secured to the upper part of the stem substantially as set forth.

6. A combination-lock consisting of a verticallymovable spring-controlled lockingplate provided with an upturned lip and downwardly-projecting pins, and revoluble register-plates provided with blind and open holes for such pins, mounted on stems having bearings in the case of the lock provided with dial-plates secured to the upper part of the stems, and a button for turning the stem, substantially as set forth.

7. In a lock of the class described, in combination with a vertically-movable lockingplate provided with a downwardly-projecting pin, a revoluble stem provided with a register-plate having a perforating hole near its periphery, a circular dial-plate furnished with characters adjustably secured to the stem, and a mark on the top plate of the look by which the dial-plate is set so as to bring the hole in the register-plate into alinement with the pin on the locking-plate, substantially as set forth. 7

8. In a lock of the class described, in combination with a locking-plate provided with a downwardly-projecting pin a revoluble stem provided with a circular register-plate having one open and a number of blind holes, a circular dial-plate furnished with an equal number of characters with all of the holes, and having in its center an equilateral po- ITO In testimony whereof I have hereunto set my hand this 16th day of January, 1896.
